You and your kids can astound your friends and family with three easy egg science “eggs-periments.” All it takes is one secret ingredient and a little patience.

In this article I’ll show you how to remove the hard eggshell to discover what lies beneath an egg’s tough exterior.

Why Remove the Eggshell?

Scrambled, boiled, sunny side up… naked? Most kids (and grownups, too) are familiar with the many things you can do with eggs. Wouldn’t it be fun to try something with an egg that you’ve never seen before?

This experiment doesn’t have fire or explosions or bright colors or noises, but it does contain some cool lessons on chemical reactions and osmosis.

Removing the shell may be completely embarrassing for the egg, but it will be fascinating for you and your kids.

Show them the awesome destructive power of the earth with a slippery, oozing goo they’ll love to get their hands in.

In this article I’ll show you how to make Glacier Goo—a type of Silly Putty that will demonstrate the movement of glaciers.

Why Make Glacier Goo?

Glaciers are pretty fascinating things: massive, moving, blue-and-white mountains of ice that destroy nearly everything in their paths, creating landforms such as U-shaped valleys, moraines and kettle lakes, to name a few.

For hundreds of thousands of years, the movement of glaciers has shaped land through erosion and deposition.

Glacier Goo is a really cool way to learn how glaciers transform the earth and literally move mountains—and you don’t have to wait a thousand years to see the results.

How about creating a fun activity that shows your kids why we are all different yet very much the same.

The project is creating edible DNA.

In this article, I’ll help you explain the molecule of life that is DNA in kid-friendly terms, show you how you and your family can discover some of your unique genetic traits and teach you to make a delicious model of the DNA strand that your kids will love.

Why Should We Learn About DNA?

Has your daughter ever wondered why she can roll her tongue but her best friend can’t, no matter how hard she tries?

Or why you’re left-handed but everyone else in your family is right-handed?

Maybe your son wishes his curly hair was straight like his sister’s?

What causes all these differences, even between siblings who have the same parents?

The answer lies in our DNA, a special kind of molecule that holds the code—the instructions—for every cell in our bodies.

We all like to remind our children that they are unique and special: “There is only one You,” we tell them. “There can never be another You!” DNA is what makes this true. DNA determines the characteristics that make each of us different from anyone else in the world. What a sweet concept.

It’s also a very important scientific concept, which may open your children’s eyes—whether they’re blue, brown, hazel or green—to the discovery of their own special traits such as blonde hair or large feet or brown skin.
